Namespace: OIV.Inventor
Assembly: OIV.Inventor.SbLinear (in OIV.Inventor.SbLinear.dll) Version: 9.9.39.0.Release.27472774f05218f47d897e52c3791dccca1041b1

Syntax

C++

Copy

public float GetWorldToScreenScale(
	ref SbVec3f worldCenter,
	float radius
)

Public Function GetWorldToScreenScale ( 
	ByRef worldCenter As SbVec3f,
	radius As Single
) As Single

public:
float GetWorldToScreenScale(
	SbVec3f% worldCenter, 
	float radius
)

member GetWorldToScreenScale : 
        worldCenter : SbVec3f byref * 
        radius : float32 -> float32

Parameters

worldCenter: Type: OIV.InventorSbVec3f
Center in world coordinates.
radius: Type: SystemSingle
Radius in normalized screen coordinates.

Return Value

Type: Single
Scale factor.

Remarks

The sphere would appear to have the given radius in normalized screen coordinates when projected onto the near plane.
